Help functions for IDL typecodes

This module contains some functions that gives support in creating
IDL typecodes that can be used in for example the any types typecode field.
For the simple types it is meaningless to use this API but the functions exist
to get the interface complete.

The type TC used below describes an IDL type and is a tuple according
to the to the Erlang language mapping.

Functions

null() -> TC

void() -> TC

short() -> TC

unsigned_short() -> TC

long() -> TC

unsigned_long() -> TC

long_long() -> TC

unsigned_long_long() -> TC

wchar() -> TC

float() -> TC

double() -> TC

boolean() -> TC

char() -> TC

octet() -> TC

any() -> TC

typecode() -> TC

principal() -> TC

These functions return the IDL typecodes for simple types.

object_reference(Id, Name) -> TC

Id = string()

the repository ID

Name = string()

the type name of the object

Function returns the IDL typecode for object_reference.

struct(Id, Name, ElementList) -> TC

Id = string()

the repository ID

Name = string()

the type name of the struct

ElementList = [{MemberName, TC}]

a list of the struct elements

MemberName = string()

the element name

Function returns the IDL typecode for struct.

union(Id, Name, DiscrTC, Default, ElementList) -> TC

Id = string()

the repository ID

Name = string()

the type name of the union

DiscrTC = TC

the typecode for the unions discriminant

Default = integer()

a value that indicates which tuple in the element list that is default (value < 0 means no default)

ElementList = [{Label, MemberName, TC}]

a list of the union elements

Label = term()

the label value should be of the DiscrTCtype

MemberName = string()

the element name

Function returns the IDL typecode for union.

enum(Id, Name, ElementList) -> TC

Id = string()

the repository ID

Name = string()

the type name of the enum

ElementList = [MemberName]

a list of the enums elements

MemberName = string()

the element name

Function returns the IDL typecode for enum.

string(Length) -> TC

Length = integer()

the length of the string (0 means unbounded)

Function returns the IDL typecode for string.

wstring(Length) -> TC

Length = integer()

the length of the wstring (0 means unbounded)

Function returns the IDL typecode for wstring.

fixed(Digits, Scale) -> TC

Digits = Scale = integer()

the digits and scale parameters of a Fixed type

Function returns the IDL typecode for fixed.

sequence(ElemTC, Length) -> TC

ElemTC = TC

the typecode for the sequence elements

Length = integer()

the length of the sequence (0 means unbounded)

Function returns the IDL typecode for sequence.

array(ElemTC, Length) -> TC

ElemTC = TC

the typecode for the array elements

Length = integer()

the length of the array

Function returns the IDL typecode for array.

alias(Id, Name, AliasTC) -> TC

Id = string()

the repository ID

Name = string()

the type name of the alias

AliasTC = TC

the typecode for the type which the alias refer to

Function returns the IDL typecode for alias.

exception(Id, Name, ElementList) -> TC

Id = string()

the repository ID

Name = string()

the type name of the exception

ElementList = [{MemberName, TC}]

a list of the exception elements

MemberName = string()

the element name

Function returns the IDL typecode for exception.

get_tc(Object) -> TC

get_tc(Id) -> TC

Object = record()

an IDL specified struct, union or exception

Id = string()

the repository ID

If the get_tc/1 gets a record that is and IDL specified
struct, union or exception as a parameter it returns the
typecode.

If the parameter is a repository ID it uses the Interface Repository
to get the typecode.
